<affected>
<package name="app-office/gnumeric" auto="yes" arch="*">
<unaffected range="ge">1.4.3-r2</unaffected>

<background>
<p>
The Gnumeric spreadsheet is a versatile application developed as
part of the GNOME Office project. libpcre is a library providing
functions for Perl-compatible regular expressions.
</p>
</background>
<description>
<p>
Gnumeric contains a private copy of libpcre which is subject to an
integer overflow leading to a heap overflow (see GLSA 200508-17).
</p>
</description>
<impact type="normal">
<p>
An attacker could potentially exploit this vulnerability by
tricking a user into opening a specially crafted spreadsheet, which
could lead to the execution of arbitrary code with the privileges of
the user running Gnumeric.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Gnumeric users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-office/gnumeric-1.4.3-r2&quot;</code>
</resolution>
